CHARLES V. WALKER, OF BOZEMAN, MONTANA.

SASH-FASTE NEIR Application filed October 7, 1907.

To all whom it may concern:

Be it known that I, CHARLES V. WALKER, a citizen of the United States,residing at Bozeman, in the county of Gallatin and State of Montana,have invented certain new and useful Improvements in Sash-Fasteners; andI do declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which itappertains to make and use the same. 7

This invention relates to improvements in saslrfasteners.

The object of the invention is to provide a sash-fastener by means ofwhich a window sash. may be supported and automatically locked in anydesired position.

A further object is to provide a device of this character which will besimple, strong, durable and inexpensive in construction, efflcient andreliable in operation and well adapted to the purpose for which it isde- Signed.

With these objects in view, the invention consists of certain novelfeatures of construction, combination and arrangement of parts as willbe more fully described and particularly pointed out in the appendedclaims.

In the accompanying drawings, Figure 1 is a vertical sectional viewthrough one side of a window sash and frame, showing the application ofthe invention thereto to support and lock the sash in a raised positionFig. 2 is a similar view showing the position of the fastener to lockthe window in a closed position; Fig. 3 is a horizontal sectional viewthrough 'one side of the sash, and a portion of the window frame; Fig. 4is an inner edge view of one side of the sash; and Fig. 5 is an outeredge view of the same.

Referring more particularly to the drawings, 1 denotes the sash, and 2denotes the side of the window frame in which the sash is mounted. Inone of the side rails, 3, of the sash, adjacent to its outer edge, isformed a recess, 4, the inner wall of which is inclined inwardly fromits upper and lower ends, thus providing bearing surfaces, the object ofwhich will hereinafter appear. In the side rail, 3, of the sash,adjacent to the upper end of the recess, 4, is formed an obliquelydisposed passage, 5, which extends from the inner edge of the railthrough the same and communicates at its inner end with the upperportion of the recess, 4, as shown. In the Specification of LettersPatent.

passage, 5, at the outer end of the Same, is arranged a wearing sleeve,6.

In the recess, 4, is arranged a locking or fastening device, which ishere shown and is preferably in the form of a circular disk orcylindrical metal block, 7, in one side of which is formed a slot, orrecess, 8, through which extends the end of a flexible operatingelement, 9, the inner end of which is suitably secured to the oppositeside of and eccentric ally to the disk, 7, thereby permitting said diskto roll to a limited extent on the bearing surfaces formed by theinclined inner wall of the recess, 4, when said disk is drawn up or letdown by the flexible connection, 9. The flexible connection 9 is hereshown and is preferably in the form of a chain and extends through thepassage, 5, and is provided on its outer end with a ball, or bead, 10,which prevents said end of the chain from passing into the outer end ofthe passage, and also rovides a suitable grip by means of which thechain may be readily grasped to operate the disk, 7.

In operation, when it is desired to raise the window, the chain 9 ispulled outwardly, thus raising the disk, 7, to the center or widest partof the recess, 4, in which position the disk is entirely within therecess and does not engage the adjacent edge of the window frame. Afterthe window has been raised to the desired extent, a further pull isapplied to the chain 9, which will draw the locking disk upwardly intoengagement with the upper inclined wall of the recess, 4, wherein thesame will be tightly wedged between said wall and the adjacent side ofthe window frame, thus providing a chock, or wedge, which will tightlyhold the window frame 1n an'elevated osition. When it is desired tolower the wmdow sash, the same is lifted to a sufficient extent todisengage or loosen the disk, 7, from between the inclined upper wall ofthe recess and the adjacent siole of the window frame, after which saidblock may be lowered by the chain 9 of the central portion of the recessand out of engagement with the adjacent side of the win dow frame, thuspermitting the sash to be readily lowered. The sash is locked in itslowered position by allowing the disk 7 to drop down into engagementwith the .lower inclined wall of the recess, 4, wherein the same willbecome wedged between said wall and the adjacent side of the windowframe,

which will prevent the raising of the window until the disk or block isagain pulled up by means of the chain, 9, as hereinbefore described.

Having thus fully described my invention, what I claim as new and desireto secure by Letters-Patent, is:

In combination with a window frame and a sash apertured in the edge toform a twin pair of oppositely inclined wedging walls, said sash havingan edgewise channel connecting with the aperture therein, of a wedgingdevice adapted to operate over said inclined Walls, said wedging devicecomprising a pair of spaced disks, an integral bridgepiece connectingsaid disks at their lower ends, a chain having its end link secured tothe bridge-piece to pass through said channel, and a handle on the chainat the opposite end to the disks.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.

CHARLES V. WALKER.
